ATI Radeon X850 XT Mac Edition

"Apple Online Store has added the ATI Radeon X850 XT as a Configure To Order (CTO) option on new G5 Power Macs. In addition, they have dropped the nVidia GeForce 6800 Ultra and replaced it with the 6800 GT, a slower card. We don't have either of the new cards in the lab right now but we can give you an idea of how they will perform based on past testing of the 6800 GT and an overclocked Radeon X800 XT (that's running at the same speed as the X850 XT)."Story
